Review: Hard to find a strain wave gearbox for NEMA17 at this price. Working well with plenty of torque, no discernable backlash (I have not done any precision measurements). A bit of roughness if I backdrive it, but this is not a problem for my application. The bit of gear grease it comes with was a handy addition. Overall I'm happy with it.

## Features

- Directly Fits Nema 17 Stepper Motor: considering the wide application of the stepper motor, the harmonic gearbox comes with a customized flange to connect with Nema 17 stepper motors, and it’s easy to assemble, making it easy to work for your application.
- Harmonic reducer utilizes a unique operating principle that is based on the elastic mechanics of metals, one of the biggest advantages is the harmonic drives approach to zero-backlash and the weight and space savings compared to other reducers.
- Strain wave harmonic gearing is widely used for industrial robots, CNC equipment, medical instruments, and the automation industry. the high torque strain wave gearbox has 30/50 gear ratio and provides a harmonic gear reduction.
- The strain wave drive technology makes the reducer come with more great features, like low backlash, high torque, high reduction ratio, compact size, excellent positional accuracy and repeatability accuracy
